Baby Gammy: Australian parents 'wanted him'

An Australian couple have denied abandoning a baby born with Down's syndrome to a surrogate in Thailand and have said they would fight to get him back.

David Farnell and his wife, Wendy, have insisted that the surrogate mother refused to give up the seven-month-old baby boy, who is called Gammy. They took his twin sister.
